Coronal

Coronal Technologies (coronal.tech) is an advanced manufacturing startup headquartered in Long Beach, California, specializing in plasma arc additive manufacturing of superalloy components. The company uses a proprietary plasma arc process to melt wire feedstock and print near-net-shape components from titanium, refractory alloys, and other difficult-to-process materials. Their technology offers higher deposition rates and broader material compatibility than competing additive manufacturing methods, enabling the production of complex, high-performance parts for use in extreme environments.

Coronal serves customers across the energy, aerospace, defense, marine, and semiconductor manufacturing sectors. By dramatically reducing lead times - by 30 or more weeks compared to traditional manufacturing - and minimizing raw material waste, Coronal addresses critical bottlenecks in the supply chains of industries that depend on precision superalloy components. For the US energy sector specifically, Coronal's ability to rapidly produce novel components from difficult alloys is essential for building next-generation clean energy systems that demand extreme durability and precision.

As an early-stage, privately held company with a small but focused team, Coronal represents an emerging player in the advanced materials and manufacturing segment of the US energy supply chain. Its technology reduces dependence on traditional forging and machining processes that are often slow, costly, and reliant on overseas suppliers - making it strategically significant for domestic energy and defense industrial resilience.
